V The present invention relates to aportable starter for heavy internal combustion 'engines and: has for its prime object to provide a mobile structure of theautomobile type with means incorporatedtherewith so that the same may be utilized: in" starting heavy'internal combustion engines whic-hare extremely diflicult to: crank,

Another very important object of the invention residesin the provision of a portable starter of this naturewhicliis comparatively simple in'its construction, easy tofm'anipin late,thoroughly' efficient and reliable 'in use and operation, and otherwise well adapted to the purpose for which it is designed. 1 I With the aboveand numerous other ob -jects in View as will appear as the descriptionproceeds, the invention resides in cer tain' novel features of construction, and in the combination and arrangement of parts I as will be hereinafter'more fully described and claimed. V

In the drawing: v Figure l is a topplan View of the apparatus embodying the features of my invention, 7 r

F igure 2 1s a side elevatlon thereof, Flgure 3 is a detail sectional view taken Figure 4 is a perspective view of a spring mount bar, f

Figure 5 is a'perspectiv'e view of a rod, Figure 6 is a sectional view taken substantially on the line 6-6 of Figure 1, and g 55 Figure 7 is'a perspective View of a plate.

Referring to the drawings in detail 'it will be seen that the invention consists of 1 a small, or miniature automobile of narrow 'gauge denoted generally by the letter A,

V capable of travelling and proceeding by means of its own power, generated by gaso-V line, kerosene, naptha or any other com- 'bustible fuel englne or motor, (not shown) under a suitable hood 5.

45 The power generated by the engine is transmitted in the 'usual way to rear wheels 6 and 7 throughthe elements commonly known as transmission gears, transmission shafts, diflerentialetc. On the right rear 56 Wheel 6 of this conveyance is attached and E -tending through a tubular V of the "frame '36 "and disposed horizontally along the; rear of the conveyance is a shaft 37' andsecured to one endofthisshafU-S'Z 05' and depending therefrom; is a lever" 8 (see Figure Fixed onth'e" other end" of; the

rigidly held thereto by suitableme'ans'a friction pulley 2, the outer end of the pulley being provided with a reduced cent-rally located projection which is-free to rotatein bearing 4 on the adjacentend of the-55 brace 35. v 'Thisbrace forms a; part-' offrame 36 which is permanently secured to" the convey'ance'by, suitable meansso that the frame 36'be'comes a part of and moves-with said conveyance at all times.

person 40 shaft 37 andextending upwardly therefrom hen the heavy duty "engine indicated in dotted lines 1 in Figures l and Z is to" be started, the conveyance is? driven alongside parallel to the'engine base and the rearof the conveyance isthen lifted and placed upon the'rolling'd'ol-l-y truck 12 1 A nut 13 is then removed from the foundation bolt 1 14 0f the engine; lunged strap 15 is placed over thebolt lt an'd nut 13 is replacedandscrewed downf firmlyt p I sliding member 42 including a rod lfi is adjustably connected with the l'everj8, the

member 42 being bifurcated and" having "a plurality of'openings 1 7 so that a pin 43' may be inserted} therethrough-and' through the extremity of the lever 8. Friction brake '18 is then applied to-the left rear wheel 7 i I 1 f the conveyance and. is s t'ifliciently v tight The hinged base 21 of course, is hingedly connected with the strap 15. The spring 20, in an effort to resist compression, draws the conveyance on the rolling truck 12 slightly forward thereby frictionally and resiliently engaging the pulley 2 with the engine fly wheel 28 thereby causing the fly wheel 23 to revolve.

The engineer, of course, may then regulate the fuel supply, ignition, etc., of the heavy engine until the same, starts. l fhen the heavy engine starts, the lever 11 is then released thereby relieving frictional engagement of pulley 2 and fly wheel 28. The strap 15 is then removed and the dolly truck 12 is removed from under the conveyance. The work may thus be accomplished by one man instead of several are often required and without risk of life and limb as compared with the present method of revolving heavy engine fly wheels by hand.

It is thought that the construction, operation, utility and advantages of the invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been disclosed in considerable detail merely for the purpose of exei'nplilication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arangement of parts may beresorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. In combination, an automobile conveyance including a pair of rear drive wheels, mobile means associated with the conveyance for holding said drive wheels raised from the ground, a pulley on one of the drive wheels, a brake for the other drive wheel, and manually operable resilient means for shifting the conveyance in a manner to operatively engage the pulley frictionally with an engine fly wheel, said means including an anchoring device, a lever, and means for .adjustably connecting the lever to the anchoring device.

2. In combination, an automobile conveyance comprising a pair of rear drive wheels, mobile means for holding said conveyance raised with the drive wheels off the ground, a pulley on one drive wheel, abrake on the other drive wheel, frame, means for attaching the frame tothe conveyance, a shaft rockable in the frame, a crank on the shaft, resilient connecting means between the crank and the base of an engine to be cranked, and means for rocking the shaft to tension the connecting means to urge the conveyance in a direction to resiliently and frictionally hold its pulley against the fly wheel of the engine to be cranked.

3. In combination, an automobile conveyance comprising a pair of rear drive wheels, mobile means for holding said conveyance raised with the drive wheels off the ground, a pulley on one drive wheel, a brake on the other drive wheel, a frame, means for attaching the frame to the conveyance, a shaft rock able in the frame, a crank on the shaft, resilient connecting means between the crank and the base of the engine to be cranked, and means for rocking the shaft to tension the connecting means to urge the conveyance in a direction to resiliently and frictionally hold its pulley against the fly wheel of the engine to be cranked, said connecting means comprising a pair of hingedly connected members one anchored to the base and the other having a pair of ears rising therefrom, a rod slidable through the ears, a spring on the rod between the ears impinging against one ear and a collar on the red, one end of the rod beingbifurcated and provided with a plurality of openings, and a pin extending through one of the openings and through the crank.

In testimony whereof I affix my signature.

JAMES M. DAVIS.
